SNOW-SCRAPER.

SPECIFICATION formlng part of Letters Patent No. 768,749, dated August 30, 1904.

Application filed March 26, 1904:. Serial No, 200,151- (No model.)

To all 1071 0771, it may concern:

Be it known that I, MILFORD C. HOPPER, a citizen of the United States, residing at Woburn, in the county of MiddleseX and State of Massachusetts, have invented an Improvement in Snow-Scrapers, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to a snow-scraper which has been specially designed for clearing ice-fields of snow, although the invention may be used generally for scraping snow or other material.

The device comprises a scoop or scraper having suitable handles and having pivoted to each side runner members, said members having in turn pivoted thereto the draft-links to which the team is applied.

The rear end of the runner members has pivotally connected thereto a trailing platform on which the operator stands while the scraper is in operation, the parts being so arranged that the weight of the operator serves to hold the scraper in scraping position.

The relation between the pivotal point of the draft-links and runner members is such that when the platform is relieved of the weight of the operator the pull on the draft links turns the runner members and scoop bottom side up, said runner members in this position acting as runners to support the scoop. I

The device is lowered and thrown into operative position by the operator placing his toe on the end of the trailing platform and forcing the spikes therein into the ice. This prevents forward movement of the trailing attachment, and the draft on the draft-links then serves to throw the scoop and runner members back into operative position.

In the drawings, Figure l is a side view of my improved scraper, showing the parts in operative position. Fig. 2 is a similar view showing the scraper dumped. Fig. 3 is a plan view.

The scraper or scoop itself is designated by 3 and may be of any suitable shape and size,

it having suitable handles 4 to be grasped by the operator.

Pivoted to each side piece of the scoop or scraper 3 is a runner'member 5, which preferably has the rounded front portions 6 and has the shoe portion 7, on which the weight of the parts rest when the scoop is dumped, as will be presently described. The runner members are pivoted to the side pieces in any suitable way, as by means of the pivot-pin 8, and pivoted to each runner member is a draftlink 9, to which the usual draft-chain 10 is secured.

The draft-links 9 are preferably located between the runner members 5 and the sides of the scoop, as seen in Fig. 3, and the pivotal point 11 of each draft-link is situated back of and preferably slightly above the pivotal point 8 of the corresponding runner member when the parts are in their operative position, as best seen in Fig. 1. Pivotally connected to the rear end of said runner members is a trailing platform 13, on which the operator stands when the device is in operation, said trailing platform having its rear end beveled, as at 14:, and the beveled portion provided with suitable spikes 15, which do not engage the ice when the trailing platform rests flatly thereon, as seen in Fig. 1. The purpose of these spikes will be presently described.

Any suitable way of connecting the trailing platform to the runner members may be employed, and, as herein illustrated, said runner members are connected at their rear ends by a cross-rod 12, to which the front end-of the platform 13 is pivoted.

16 designates chains or other suitable flexible connections connecting the handles 4 to the front end of theplatform 13.

Fig. 1 shows the device in position for scraping, it being understood that the operator stands on the platform 13 and that the team or other motive power is hitched to the draftchains 10.

The weight of the operator is suflicient to hold the rear ends of the runner members down against the surface being scraped and the platform 13 flat against said surface. Since the scoop 3 is pivoted to the runner members, the operator can tip it more or less, as required in performing the scraping operation. I'Vhen the scoop has been filled and is ready for dumping, the operator merely steps off from the platform 13, and as soon as said platform is relieved of its weight the pull on the draft-links causes the runner members and scoop to turn completely over into the position shown in F ig. 2, for since the point where the power is applied to the scoop is some distance above the surface being scraped the resistance to the scraping is suflicient when the platform 13 is relieved of its weight to cause the runner members and scoop to roll over the rounded ends 6 of the runners and into the position shown in Fig. 2. In this position the scoop is supported entirely above the ground by the runner members and the latter rest upon their shoe portions 7.

The draft-links 9 are each provided with the nose portion 18, which engages the pivotal bolt 8 of the corresponding runner memher when the scoop is dumped. The dumping of the scoop also carries the trailing platform 13 into substantially the position shown in Fig. 2, in which position the spikes 15 come in contact with the scraping-surface.

Nhen the scoop has thus been dumped and returned to the place where further scraping is required, the operator merely places his toe upon the end 14: of the trailing platform, and. thus embeds the spikes 15 into the ice. The resistance which the said spikes offer,

. combined with the pull upon the draft-links,

throws the runner members and scoop back into the position shown in Fig. 2, this operation being greatly facilitated by the engagement of the nose 18 of each draft-link with the corresponding pivot-bolt 8.

Various changes in the construction of the parts may be made without in any way departing from the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina device of the class described, a scoop, runner members hinged to its sides, draft devices connected to said runner members, and a trailing platform hinged to the rear ends of the runner members.

2. In a device of the class described, a scoop,

runner members hinged to its sides, draft- I links hinged to said runner members between flexible connections between the handles and front end of the said platform.

4. In adevice of the class described, ascoop, a runner member hinged to each side, each runner member having a shoe portion on which the device rests when it is down, a draft-link hinged to each runner member between its ends, and a trailing platform hinged to the rear end of said members.

5. In adevice of the class described, a scoop, a runner member hinged to each side, each runner member having a shoe portion on which the device rests when it is down, a draft-link hinged to each runner member be tween its ends, and a trailing platform hinged to the rear ends of said members, said platform having spikes in its rear end.

6. In adevice of the class described, a scoop, runner members hinged to its sides, a d raftlink pivoted to each runner member back of and slightly above the pivotal point of said runner member with the scoop, each draft link having a nose portion, and a trailing platform pivoted to the rear end of said runner members.

7. In adevice of the class described, a scoop, runner members hinged to its sides, a draftlink pivoted to each runner member back of and slightly above the pivotal point of said runner member with the scoop, each draftlink having a nose portion, and a trailing platform pivoted to the rear end of said runner members, said platform having spikes in its rear end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MILFORD C. HOPPER.
